Lossless Scaling -lsfg 3-
LSFG 3 operates as an overlay application that sits between the game and the Windows Desktop Window Manager (DWM).
LSFG 3 is a machine-learning-based frame generation technology designed to increase frame rates and improve motion fluidity in PC games. Unlike vendor-specific solutions (like DLSS 3 or FSR 3), LSFG 3 is "GPU Agnostic," meaning it works on virtually any modern graphics card (NVIDIA, AMD, Intel, or even integrated graphics). It functions by inserting artificially generated frames between traditionally rendered frames.
| Setting | Recommendation for LSFG 3 |
|---------|----------------------------|
| Scaling Mode | Auto (or Custom if you need aspect ratio control) |
| Scaling Type | LS1 or FSR – use LS1 for crisp pixel art/2D, FSR for 3D games |
| Frame Generation | LSFG 3.0 (not 2.2 or Off) |
| Mode | X2 (most stable), X3 / X4 if you have high base FPS (e.g., 75+ → 225+) |
| Max Frame Latency | 1 or 2 (lower = better response, higher = smoother gen) |
| Resolution Scale | 90-100% (lower = better perf but softer image) |
| Cursor | Keep as is or hide if gets doubled |
| Capture API | DXGI (most stable) – change to WGC if DXGI flickers | Lossless Scaling -LSFG 3-
Gaming laptops often thermal throttle. LSFG 3 allows you to lock your game to a cool, stable 48 FPS (saving battery and heat) while your display shows 144 FPS.
Before diving into LSFG 3, it is important to understand the host application. Lossless Scaling is a $7 (or regional equivalent) application available on Steam. Unlike NVIDIA DLSS or AMD FSR, which require game integration, Lossless Scaling works as an overlay on any game or video. LSFG 3 operates as an overlay application that
It offers two primary functions:
Lossless Scaling (LS) is a utility software developed by Ths about to provide frame rate upscaling and frame generation for games and applications that do not natively support these technologies. The release of LSFG 3 (part of version 2.8 and subsequent updates) marks a significant evolution in the software’s capability. | Setting | Recommendation for LSFG 3 |
Unlike its predecessors, which relied heavily on basic optical flow or simple frame interpolation, LSFG 3 utilizes advanced optical flow algorithms to generate intermediate frames with significantly higher fidelity and lower artifacting.
